Istanbul and São Paulo Time Zone Comparison
Istanbul and São Paulo are two major cities that sit in noticeably different time zones. Istanbul is Turkey's largest city and historic capital, uniquely straddling Europe and Asia across the Bosphorus strait. São Paulo is the most populous city in Brazil and the entire Southern Hemisphere, serving as the country's financial and industrial powerhouse.
São Paulo is always 6 hours behind Istanbul, with no seasonal change, since neither city's daylight saving rules shift this relationship.
